MA3J7420GL

The MA3J7420GL is a type of rectifier array, part of the larger classification of diodes. It is used to rectify alternating current to direct current. In rectification, an AC voltage is transformed into a DC voltage waveform by converting waveform peaks over a certain voltage threshold into a continuous series of similar pulses. In this way, the MA3J7420GL can provide a clean and efficient starting or running power supply.

The MA3J7420GL features an avalanche breakdown voltage of 200V, a repetitive peak reverse voltage of 200V and a continuous forward current of 1.5A. It has a power dissipation rating of 1.38W and can withstand up to 100V of peak working voltage and 13.6mA max average forward current.

The MA3J7420GL is designed for high dielectric strength, high reliability, and low forward voltage drop. It is a surface-mount device with three independent avalanche rectifier channels and soldered pins. This makes it suitable for applications which require a complex yet reliable rectifier array.

The MA3J7420GL is commonly used in power supplies, audio circuits, and battery-charging circuits. Its low forward voltage drop and efficient rectification qualities make it suitable for use in a variety of circuits and set-ups.

The MA3J7420GL features a three-phase rectifier bridge with two diodes in parallel, making it able to provide both full-wave and half-wave rectification.

The MA3J7420GL’s working principle is based on a phenomenon called ‘avalanche breakdown’. Avalanche breakdown occurs when a diode’s electric field is strong enough to cause an avalanche of electrons to be released from the diode. During this process, the diode’s curved PN junction is changed from a semi-conducting region to an insulator.

The MA3J7420GL is able to efficiently transform AC voltage into DC voltage by generating a large number of free electrons and ‘shoving’ them into a semiconductor region. This creates a charged space and increases the electrical field across it, preventing the current from flowing in the opposite direction.

Overall, the MA3J7420GL is a reliable, efficient, and cost-effective choice for rectification purposes in a wide range of applications. Its low power consumption and straightforward installation make it highly sought after for its versatile use and large number of convincing features.
